Active clinical trials for "Osteoarthritis"

The aim of this study was to investigate the pharmacokinetics of free and total ropivacaine after unilateral and bilateral TKA. A population model was successfully built and peak free ropivacaine concentration stayed below previously proposed toxic thresholds in patients undergoing unilateral as well as bilateral TKA receiving LIA with high dose ropivacaine.

Knee Osteoarthritis (OA) is one of the most common conditions causing disability and limitation in the elderly population, with 13% of women and 10% of men over the age of 60 suffering from symptomatic knee osteoarthritis. Pain and other symptoms of OA significantly affect the quality of life, manifesting itself in pain, decreased range of motion, functional limitation and change in gait patterns. Total Knee Replacement Surgery (TKR) is the most common solution for patients with advanced cartilage erosion and is considered a successful surgery with high satisfaction rates (about 80%). The surgery becomes necessary when pain limits the daily functioning and impairs the quality of life and after the failure of conservative treatment. Still, patients undergoing TKR suffer in the first period after surgery from pain, decreased balance and proprioceptive impairment. Despite the improvement in pain and function, the rates of falls after surgery do not change drastically and remain high. About a third of older adults fall each year, leading to fractures, functional decline and in some cases death. Walking is a complex task, and with advancing age walking becomes less automatic and requires additional attention. Among adults, it is known that an increased risk of falls is associated with reduced ability to perform complex walking tasks, such as walking while talking or crossing obstacles. After TKR, most falls occur while walking due to slipping / tripping. In addition, proprioceptive impairment, pain and poor balance are associated with an increased risk of falling after TKR. The mechanism underlying these effects may be increased allocation of cognitive resources to walking. Thus, this study will examine the ability of people before and after TKR to perform complex walking tasks, in order to examine the change in attention allocation to walking following surgery. It is hypothesized that after surgery, the ability to walk while performing an additional task will be lower than prior to surgery.

The origin of knee osteoarthritis is multifactorial but the disease is strongly related to age. The pain and functional disability are the main reasons for consultation. Non-pharmaceutical treatment is always indicated. The rehabilitation will reduce the pain, maintain or partially recover the amplitude of the movements as well as fight against vicious analgesic attitudes and strengthen the muscles to stabilize the joints. A program of self-rehabilitation exercises performed at home may be prescribed to people with knee osteoarthritis. It must include exercises adapted to the patient's functional abilities and painful level and requires education to improve the patient's motivation to practice a regular exercise program. However, adherence to such exercises is low, and until 2016 there was no objective way to find out the reasons for patients' lack of adherence to self-workout programs. The EARS ("Exercise Adherence Rating Scale" or Adhesion to Physical Exercise Programs) is validated in 2016 and reliable to evaluate the physical activity of patients with low back pain. As far as we know, this questionnaire is the only one validated in the international literature, a validation for French patients is currently underway. We believe this tool can be used for patients with knee osteoarthritis after minor changes.

The aim of the study to investigate any relation with functional parameters and femoral cartilage thickness evaluation by ultrasonography in lower extremity amputate individuals.

Aim To investigate associations between within-person change in patient reported outcomes (PROMs) and wish for joint surgery during up to 12-month participation in a digital first-line intervention for knee and hip osteoarthritis (OA) comprising exercise and education. Methods Retrospective observational registry data. All participants enrolling between June 1st 2018 and September 30th 2021 with follow-up data and with a change in their wish for surgery (dichotomous, becoming wishing or unwishing) were included. Analysed PROMS comprised pain (numeric rating scale (NRS), 0-10), 5 level EuroQol - 5-dimension (EQ5D-5L, 0.243-0.976), overall health (NRS, 0-10), activity impairment (NRS, 0-10), walking difficulties (yes/no), fear of movement (yes/no), function and quality of life subscales of Knee/Hip injury and Osteoarthritis Outcome Score 12 Items (KOOS-12/HOOS-12, both 0-100). To capture effects of changes in PROMs over time on probability of wish for surgery, the investigators used fixed effect (conditional) logistic regressions.

Questionnaires are often irreplaceable tools of collection of information in research and in the clinical practice. Coupled with other measures, they can be simple complementary tools, but questionnaires are sometimes the only way to collect data, such as self-service efficacy. The objective of this study is a validation of the French translation of the ASES. To guarantee the comparability between the original version and the translated version, the translation of a questionnaire supposes two essential stages: a literal translation and an adaptation to the cultural context, to the habits of life and to the idioms of the target population. This new version will afterward be validated with patient's troop.

The purpose of this study is to correlate functional outcomes and perioperative complications with tourniquet use during total knee arthroplasty.

This is a substudy to a randomised trial investigating the effect of liraglutide on body weight and pain in overweight or obese patients with knee osteoarthritis (NCT02905864). In the parent trial, patients will be subjected to an 8-week diet intervention phase including a low-calorie diet and dietetic counseling, after which patients will be randomised to receive either liraglutide 3 mg or liraglutide 3 mg placebo as an add-on to dietetic guidance on re-introducing regular foods and a focus on continued motivation to engage in a healthy lifestyle. This substudy aims to investigate any changes in Ultrasound (US) measures associated with the initial 8-week weight loss intervention.

The need for a tool to measure flare in lower limb osteoarthritis (OA of the hip and knee) is justified by the opportunities for development of clinical trials targeting hip and knee OA long-term treatment (slow acting drug, disease modifying drug) and short-term treatment of symptoms. Such treatments are currently under development and will likely bring important changes in the treatment of patients. The development of a Flare-OA tool would be essential to capture the occurrence of flare, and to implement and adapt treatment strategies. This project was elaborated with the aims to: define the construct through development of a conceptual framework use the conceptual framework to inform the development of a patient-reported outcome measure, Flare-OA tool, for people with OA evaluate the psychometric properties of the new measure using the OMERACT (Outcome Measures in Rheumatology) filter 2.0 and Rasch measurement methods.

The primary purpose of this study is to demonstrate the POLARSTEM™ Ti/HA cumulative femoral stem revision rate at 10 years. The secondary purpose of this study is to provide 10 years of safety and effectiveness data of POLARSTEM™ Ti/HA in terms of radiographic and clinical performance
